Question

Which one of the following is planar?

• A. $XeF_4$
• B. $XeO_4$
• C. $XeO_3F$
• D. $XeO_3F_2$

Answer 1

Answer: (A)

$XeF_4$

Answer 2

Structure of $XeF_4$ is as follows It involves $sp^3 d^2$ hybridisation in Xe-atom . The molecules has square planar structure. Xe and four F-atoms are coplanar. The lone pairs present on axial positions, minimise electron pair repulsion.
